EVAPGRATING TANK.

Application filed January 20. 15526. Serial No. 852,55

This invention relates to evaporating tanks, and more particularly to steam jacketed tanks for drying calcium carbide residue in the n'ianufacture of acetylene gas. The principal object of the invention is to provide means for effecting a rapid reduction of liquid carbine residue to a solid mass by evaporating the water from the carbide residue by means of a steam jacketed container.

Another object of the invention is to provide a plurality of evaporating tanks which are adapted to receive the carbide residue in a liquid state from a like number of generating tanks which are positioned directly above the evaporating tanks whereby the liquid carbide residue may be transferred from the generating tanks to the evaporating containers and quickly reduced to a solid mass, and then removed from the said evaporating containers in any of the well-known manners.

A further object of the invention is to provide a device as specified, which accomplishes the purpose set forth in a rapid manner, thereby reducing to a minimum, the expense of disposing of carbide residue in the manufacture of acetylene gas on a large scale.

Other objects of the invention in the following detail description, and in the accompanying drawing wherein:

Figure l is an end elevation of the device in assembled relation.

Figure 2 is a top plan of the evaporating tanks per se and partly in section.

Figure 3 is a sectional view on the line 33 of Figure 2.

Figure 4 is a fragmentary section similar to Figure 3, with the door in open position. Figure 5 is an enlarged detail view of one of the locking bolts.

Figure 6 is a section on the line 6-6 of Figure 5.

Referring more particularly to the drawings, the invention comprises a rectangular tank 10 which has riveted or otherwise secured to the bottom 11 thereof, an auxiliary bottom 12 and the side walls 18 therefor for forming a leak-proof chamber l-i under the tank 10. The. chamber 14 is provided for the safe reception of steam under pressure with a plurality of stay-bolts 15 which are equally spaced, as shown in Figure 2 of the drawings, and secured in a vertical manner between the tank bottom 11 and the auxilwill appear iary bottom 12, for reinforcing the respective bottoms which comprise the heating chamber 14. ticn is inaoeat the front end of the chamber 14:, as indicated at 16, and a steam outlet and drain therefor is provided at the rear end of the chamber 14, as indicated at 17, for return to the source of steam (not shown). 7

In order to drain a large part of the water at the top of the carbide residue shortly after it has been run into the evaporating tanks and settled, an overflow sluice l8 and gate valve 19 therefor is provided in the rear end of the said tank adjacent the top edge thereof, as indicated at 20, for sluicing or drawing the surface water oil without agitating the settled c rbide residue. After a suitable application of steam and the complete evaporation of the water from the carbide residue, the said residue is removed by means of a shovel or the like, froin the evaporating tanks, through the opening 21 in the front end of said tank. Said opening is provided with a suitable closure door 22, which is hinged to the front end of the tank, as indicated at 28, and the side edges 24; of said door are provided with a plurality of slots 25, for registration when the door 22 is in closed position, with a like number of stud bolts 26, which are hingedly connected to the tank 10 adjacent to the vertical side edges of the opening 21, for securing the closure door 22 in a lealeproof manner.

Upon the removal of the evaporated carbide residue from the tank 10, the hinged stud bolts 26 are moved out of the slots 22 in the closure door and said door is then lowered to a position, as shown in Figure 3 of the drawings, and forms a chute when in this position, by means of the side plates 27, which are secured to the inner side of the door 22 and the angularly bent free ends thereof extending into and engaging the inner face of the tank 10, for limiting the downward movement of the door 22. A suitable portion of the said side plates 27 is cut away, as indicated at 28 for providing a clearance space for the horizontal edge of the opening 21. in the front end of the tank 10, when the door 22 is in closed position.

From the above description, taken in connection with the drawings, it will be readily seen that I have provided a rapid, effective, safe, and cheap method for the disposal of carbide residue in a liquid state, and while I A suitable steam inlet connechave shoWn and described, one practical embodiment of my invention, it is to be understood, that I do not limit myself to the exact construction set forth but consider myself at liberty to make such changes and modifications as fairly fall Within the scope of the appended claims.

7 lVhat I claim is:

l. A device of the class described comprising a rectangular container, a steam chamber forn'ied on the bottom of said container, means for reinforcin said chamber, a steam inlet in the front end of said chamber, a steam outlet in the rear end of said chamber, an overflow sluice adjacent to the upper edge of the rear end of said container, a gate valve secured to said sluice, a U- shaped opening in the front end of said container, a closure plate hingedly connected to said front end of said container, and means for securing said closure plate over said opening.

2. A device of the class described comprising a rectangular container, a steam chamber formed on the bottom of said container, means for reinforcing said chamber, a steam inlet in the front end of said chamber, a steam outlet in the rear end of said chamber, an overflow sluice adjacent to the upper edge of the rear end of said container, a gate valve secured to said sluice, a U-shaped opening in the front end of said container, a closure plate hingedly connected to said front end of said container adjacent to the lower edge of said opening, vertical side members secured to the inner :face of said closure plate and extending into said container, means for limiting the opening movement of said closure plate, and means for securing said closure'plate over said opening in normal position.

in testimony whereof I alfix my signature.
